others, is of so changeable a form, that much stress is not to he laid on 

 this circumstance. In the general structure of the skeleton the B. Ca- 

 rolinae seems perfectly to agree with a young specimen of the Physalus 

 antiquorum, the skeleton and stuffed skin of which are to he seen in the 

 "jardin des Plantes" at Paris, in the neighbourhood of the building for the 

 Museum of comparative Anatomy, although that skeleton is that of a some- 

 what smaller individual, (14 metres long), with only 62 vertebrae and 14 

 pairs of ribs, (the first pair being probably lost). The agreement between 

 them in the form of the lateral processes of the cervical vertebrae is com- 

 plete. As in the case of the B. Carolinae, according to our own observa- 

 tion, the epistrophaeus has the lateral process on one side, viz. the right, 

 closed or annular, and on the other open. In this as well as in the 

 form of the phalanges great similitude prevails between B. Carolinae and 

 the specimen of lialaenojA. mmculus described by G. 0. Sars in the above 

 mentioned treatise. In this latter specimen it is true that both lateral pro- 

 cesses of the epistrophaeus were still open, but the drawing pi. 3. fig. 5 

 shows, that that of the right side was more nearly to be closed than that on 

 the left. We may therefore assume, that, in the developement of the lateral 

 processes of the epistrophaeus in tis species, it is normal that the right- 

 hand process first assumes the annular form. As regards the external form 

 of the body, the B. Carolinae, if we can rely upon the figure given by Malm 

 on the cover of the brochure referred to, presents some differences from 

 the usual type as set forth in the drawings of Schlegel, G. 0. Sars and 

 others, the snout being obtuser, and the portion where the nostrils are si- 

 tuated projecting pretty abruptly, or forming a kind of hump instead of a 

 hollow, as it is usually represented. Between Sars' and Malm's specimens 

 there is however this correspondence, according to Malm's photograph, that 

 there is a keel stretching along the upper side of the head. G. 0. Sars *) 

 states that the fishermen on Norway's western coast characterize by the 

 appellation of "Tuehval" a particular species of Finner, which is distinguished 

 from others by a large knotformed protuberance (Tue, hill, or Hus, house) 

 at the blowholes, and identifies it with Strom's Tuehval, and says, that 

 according to the observations of the fishermen its in- and ex-spirations pro- 

 duce a peculiar dull sound, which seems to give some support to the assump- 

 tion of this protuberance being a distinctive mark of the Bal. Carolinae; 

 but in the first place the aforesaid figure, given by Malm, has in all pro- 

 bability been drawn from the Whale when already stuffed, for the photo-
